Samsung Battery Breakthrough
Fast Charging and 45% Capacity Increase
Samsung NewsRoom Announcement
SAIT (Samsung Advanced Institute of Technology) has announced a breakthrough in developing a graphene ball coating that covers the nickel-rich cathodes and lithium-based anodes.
So one would ask what is the big deal? As you increase the speed of recharging a battery, it wears down the anode and cathode. The graphene ball coating not only prevents this, but also allows for an increase in capacity to go along with the faster recharging. This improves the cyclability of charging / depleting a battery. This tech also has proven to allow for a very highly stable battery with no loss of power at 60 degrees Celsius or 140 degrees Fahrenheit which is key for any electronic device but even more so for electric auto's. Graphene is 100 times more effective than copper in conducting electricity and 140 times times faster than silicon.
Samsung says this technology allows them to take a conventional EV battery that would require 4hrs under current fast charge technology and reduce it to 12 minutes.
To quote their new release: "SAIT’s research results are covered in-depth in this month’s edition of the science journal Nature Communications in an article entitled, “Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities.”SAIT has also filed two applications for the “graphene ball” technology patent in the US and Korea."
